The dose appears to high - would consider discussing a dose decrease w/ your doctor.
Or.... It could be the medication( is that a thyroid med you listed) and the dose may be too high.
One of two things, you have hashimotos thyroiditis, or you acquired the antibodies for graves/hyper along the way. Since you were diagnosed with hypothyroid its most likely you're going through a hyper phase, which is common in HT as ones body attacks thyroid cells/tissue and they end up spilling hormone causing one to go hyper. Sorry, that's the best way I can explain it. You need to request a TPO TSI and ATG antibody test to determine if this is autoimmune related.
